Let one side be x+3 and the other side be x:
1/2*(x+3+x)*9 = 40.5
Multiply both sides by 2:
(x+3+x)*9 = 81
9x+27+9x = 81
18x+27 = 81
Subtract 27 from both sides:
18x = 54
Divide both sides by 18:
x = 3
Therefore the parallels are 3 cm and 6 cm respectively.
Check: 1/2*(6+3)*9 = 40.5 square cm

What is the solution of A TRAPEZOID?
A trapezoid is a 4 sided quadrilateral which has one pair of parallel sides of different lengths. Its perimeter is the sum of its 4 sides. Its area is: 0.5*(sum of parallel sides)*height
How do you measure area of trapezoid?
To measure the area of a trapezoid, you can use the formula: Area = (1/2) * (sum of the lengths of the parallel sides) * (height). Simply add the lengths of the two parallel sides together, multiply by the height, and then divide by 2 to find the area of the trapezoid.
What is area of trapezoid?
The area of a trapezoid is equal to half the sum of the lengths of the two parallel sides (base1 and base2) multiplied by the height. The formula for the area of a trapezoid is A = (base1 + base2) * height / 2.
Formula for trapezoid?

How do you figure out the area of a trapazoid?
-- Add the lengths of the two 'bases' (the two parallel sides). -- Multiply the sum by the height of the trapezoid. -- Take 1/2 of the product. That's the trapezoid's area.
How do you calculate the area of a trapezoid?
To calculate the area of a trapezoid, you can use the formula: Area = 0.5 * (sum of bases) * height. Simply add the lengths of the two parallel sides (bases) of the trapezoid, multiply the sum by the height, and then divide by 2 to find the area.
